Be it known that I, J QHN FRANKLIN, zen-of the United States of America,and a resident of Norwood,'in the county of Hamil ton and State .ofOhio,haveinve'nt'e'd certain new and useful ImprovementsinAntivibratorySu'pports for- Gas-Burners, of which the following is aspecification. 1

Thisinvention relates to certain improvements in antivibratory supportsfor gasburn "ers, being especially adapted for-overcoming vibrationiinstreet and'factory gas-lamps, so

as to prevent damage to the; frailincandescent mantles commonly usedupon such "lamps audthe object of the invention is to provide a deviceoft this character whichshallbe of a simple and inexpensive nature andnot liable to become'deranged or broken when in use.

The' invention consists in certaininovel tea a. I tures of theconstruction, combination, and arrangement of the sei eral,partSOf'theimproved antivibratorysupporting device,

Referring, primari1y,to Figs. 1 to 4', l indicates the gas-supply pipe,and Zindicatesthe cock controlling the flow .of "gas through the same. 3'3 indicateburnerssuppliedfrom the pipe 1 and carried oniarms 4 4,extended from opposite sides of a burner connectiou fi, betweenwhichand-the'cock-2 is arranged the improved antivibratory support,(indicated as a whole by'6.)' "The burners 3 maybeof any preferred kind,being usuallyof the Bunsentype, havingiucandescent mantles suspended'above them in awell kiiown'way,jandfthere may beflbut' one oran'yjnumber of burners'B 1 instead of two such burn ers,.as hereinshown.

The device 6 compri ses, a s shown in these'ctionalfview, Fig. 2,,acup-shaped par-torrecept'acle 7, having athreaded socket 8 at-its base,to receive the threaded upperend of the'vgas-pipe and provided with avertical,

socket 8. The stem 9 extends up above-the top,v V

of the receptacle] and forms between itself and the wallsofthe-receptacle an annular space-poi chamber 10, adapted to hold asupplyofmercury, as indicated at 11, the upper edge'or top' ofthereceptacle-wall being, by

preferencdformed with an upturned annular part with ahorizontally-projectingannular flan e 14, to which are'he'ld at sui Theby means of screws '15 or thejlike" the arms 16 of a 'sheet-metal'spring, preferably con- .struted'; as shown inFig, 4 of a single piece17 ,having four integraldivergingarms. The

central aperture of the body 17 ofthe spring servesfor the passage ofthe-threaded upper of sheet n1eta lsuch as copper, bra'ss, or other end18 of a tube ,19, which screws into the lower part2lof theburnercon-nection5 and has formed on it below its screw-threaded part anannular flange, between which and the under side of the burnerconnection 5 the body portion 17 of the spring is clam ped. In

this way it will be seen that the burners 3 3 v are held elasticallysupported over the receptacle 6, with its gas-passage communicatingtacle, so'that a seal is formed between the tube 19 and stem 9 in such away as to prevent the escape of gas from the gas-passage of the stem,such gas being thus caused to pass through the bore 20.01" the tube -19up into the burners 3above the same, By this construction it will beseen that when the parts are assembled the spring-arms '16 will afford ayielding or elastic support for the hu rner and will act as a cushionbetween the same and the gas-pipe, so that the vibrations and jarringof'the pipe will be received and neutralized, by said cushion and willnot be transmitted. to the burner, as is the case in lamps constructedin the ordinary manner. In this way it will be seen that theextremelyfrail incandescent mantles used upon the burners are protectedagainst injury from sudden jars and vibration, and the cost of.

maintaining the burner is thereby materially lessons 9.. rangement ofthe tube 19 with its lower end inclosing the stem f the receptacle actsas a stop to prevent excessive swayir movement of the burner upon itselastic suppoi t,

vwhereby damage to the spring-arms themselves is avoided, and,furthermore, the mer cury held in the chamber 10 acts not merely as aseal to prevent the escape of gas between the tube 19 and the stem 9,but also serves to. check the vibration of the burner upon its elasticsupports.

In Fig. 5 I have shown the application of the improved antivibratorysupport to an ordinary street-lamp. In this view, 22 indicates thelamp-post, and 23 the globe inclosin'g the burners, which latter may beof the kind shown in Fig. 1 and provided with incandescent mantles m.The improved antivibratory support isarranged between the gas-cock 2 andthe burner connection 5, as in the previous case, and serves to preventthe mantles from being broken or damaged when the post 22 vibrates or isshaken by the wind or from any other cause. In connection withstreet-lamps I prefer to use a gas-cock and.

It will also be seen that the armovably connected with the tip 24, andare 'co'nsequently'capable of free movement upon their supportrelatively to the said auxiliary tip. The cock 2 is a, three-way cockand when turned first supplies gas to' the auxil iary lip 24, to which amatch or torch may be ap' lied, causing the gas escaping at said tip tourn in a long jet beside the burners 3. Upon further turniugmovement ofthe cock 2 the gas is turned on to the burners 3 and is cut ofi? to theauxiliary tip 24, so that the jet from said tip 24 before beingextinguished will serve to ignite the gas at the burners. In this waythe mantles are further protected from injury, since the cock andauxiliary tip 24 being flexibly or movably connected by theautivibratory support with the burner the gas may be turned on or ofiwithout danger of unduly jarring the mantle, andthe'lighter is notrequired to apply his torch or match to the burner itself, but merely tothe auxiliary tip 24, and consequently the risk of damage upturnedbarrel-like flange 30 and inside said flange,a tubular stem 31, anannular space or mercury-chamber 32 intervening to receive the dependingtube 33 of the upper member or part 25.

mercury in chamber 32 forms a seal to prevent the escape of gas betweenthe two parts, and said parts are movably connected by bent springs 28,extending between them. Chains 29 or other like devices also connect theparts 25 and-26, so that in case of breakage of the springs 28 theburner 27 will-be supported against falling. If desired, also,

the mouth of the mercury-chamber'32 may be formed with an annularinturned li-p similar.

vibrations and jars which would otherwise be transmitted direct to theburner and its mantle, and thereby prevents damage to the mom tle andgreatly reduces the expense of maintaining the lamp. It will also beobvious from the above descriptionof the invention that the device iscapable of considerable for this reason I do not wish to be understoodas limiting myself tothe precise form and arrangement of theseveralparts herein set forth. a

Having thus described my invention, I claimr 1. A-device for overcomingvibration in gas-burners comprising a burner connect-ion, a tubular partscrewed in'tosaid connection,

tween the burner connection and the tubular part and provided withdiverging arms integral with said body portion, a, part to which -thearms of the spring are connected and which is adapted for connectionwith a gaspipe and has a gas-passage adapted for communication with thebore of said tubular part, and means for preventing the escape of gasbetween the two parts,-substantially as set forth.

2; An antivibratory supportfor gas-burners and the like comprising twoparts formed with -corresponding gas-passages and a strip of springmaterial having its central portion secured to one of said parts and itsend portions formed *into'spring-arms each extended across the spacebetween the two parts of the v support and secured to theother part ofthe 3osupport, substantially as set forth. a

3. An antivibratory support for gas-burners and the like comprising twoparts having corresponding gas-passages and a strip or pieceof springmaterial having at itscentral 35 portion a perforation, a hollow plugpassed through said, perforationand engaged with v one part of thesupport for holding the central portion of thestr'ip thereto,the endportionsof said strip being formed intospring; 4o arms each extendedacross the space between the two parts and secured to the other part ofthe support, substantially as set forth.

4. A device of the character described comprising a gas-cock, a maingas-burner and an 4.5 auxiliary tip having independent gas 'conuectionswhereby each is supplied with gas through said gas-cock, and an elasticsupporting means whereon the main gas-burner is held for movementrelatively to thesaidsq auxiliary tip, substantially as set forthfgSigned by me at Cincinnati, State of Ohio this. 13th day of January,1900.
